I see that you're already getting contradictory responses between the different places you asked this question. I can't remember the correct way to polarize ours; however, I can tell you one thing for certain. There are two typical charging systems out there in the world. I think they are called A and B. The contradictory responses you are getting is because each style of charging system requires a different way of polarizing. Again, I don't remember which style the halftrack has. I used to know, back when I was searching the internet to learn how to polarize the generator in our truck. But, I'm getting old and I guess I've replaced that info in my brain with something else. Just an fyi.
